  • DRV8874: Noise on IPROPI

    Resolved
    Part Number: DRV8874 The DRV8874 datasheet states: "The internal blanking time helps to prevent voltage and current transients during output switching from effecting the current regulation. These transients may be caused by a capacitor inside the motor…
